Intel HD Graphics P4600 are integrated graphics in the Haswell Xeon Server processors. Their performance depends on the processor they are integrated on, as the latter defines the Base and Boost Clock, as well as on the SYSTEM RAM, which defines the operating memory clock, and whether the GPU accesses a 64-bit or 128-bit memory interface. Best case scenario, the Intel HD Graphics P4600 perform slightly below Intel HD 4600 Graphics and so most modern demanding games will have to be played with the lowest settings, while a few aren't even playable.
